“Chronic laxative use can eventually cause the colon to become atonic—’worn out’ if you will—and over time lead to paradoxically worsening constipation,” says Neilanjan Nandi, MD, FACP, assistant professor of medicine and director of the Center for Inflammatory Bowel Diseases at Drexel University College of Medicine. “This can lead to increasing use of laxatives that may eventually not work. If you find yourself having to chronically use laxatives for a bowel movement, you should consult with your doctor to find out why.” Discover potential causes of constipation.

“One of the most common side effects of narcotic pain medications is constipation,” Dr. Nandi says. “Narcotic pain medications may be temporarily prescribed after surgery. Intra-abdominal surgeries (e.g. appendectomy, cholecystectomy or gallbladder removal, hernia repair) or any intervention where there is manipulation of the bowels can commonly lead to a temporary ‘paralyzed bowel’ also known as an ileus. I recommend patients begin on a bowel regimen two to three days prior to receiving pain meds to prevent significant constipation.” See 50 secrets your surgeon won’t tell you.
Don’t take them if you’re travelingYulia Grigoryeva/Shutterstock
If access to a bathroom could be at all problematic, laxatives are not your friend. “Avoid stimulant, osmotic, and lubricant laxatives prior to travel as they work more quickly and have more side effects,” says Sheetal Sheth, MD, assistant professor of Obstetrics and Gynecology at the George Washington University School of Medicine and Health Sciences. Try these tips to avoid constipation while you travel.

“Fiber-based laxatives are safe, effective, and healthy,” Dr. Nandi says. “Ironically, introducing too much fiber too quickly in your diet or bowel regimen may lead to bloating, gas, or cramping. Therefore, I recommend slowly ramping up your fiber supplementation gradually such as weekly increases in dosing. Other laxatives that we call stimulant laxatives—like bisacodyl—or saline laxatives, which often contain magnesium or phosphate, may cause bowel dependence and/or lead to marked dehydration.” Or consider trying these more natural laxatives.

It may sound counterintuitive, but you shouldn’t take laxatives if you’ve had problems with bowel obstructions in the past. “Bowel obstructions can occur from scar tissue known as adhesions from previous abdominal surgery,” Dr. Nandi says. “Therefore, laxatives are contraindicated in this condition.” Not sure what your gut issues might be?

Do be cautious about using them during pregnancySyda Productions/Shutterstock
Constipation happens during pregnancy due to all the other changes going on in your body. But you need to be careful about using laxatives. “Bulk agents and stool softeners are preferred,” says Dr. Steth. “Bulk laxatives, such as fiber and bran can be taken long term—however, these may cause unpleasant side effects including excessive gas and bloating. Stool softeners can be taken on a daily basis and are minimally absorbed systemically.” Dr. Steth recommends avoiding osmotic and stimulant laxatives during pregnancy. “Osmotic laxatives may cause excessive gas and bloating, and may lead to an electrolyte imbalance. Stimulants should only be used rarely as they can lead to intestinal cramping, uterine irritability, pain, electrolyte imbalance, and dehydration.” Learn about other changes to your body during pregnancy.

“Laxatives can unfortunately be abused with the misconception that they can help promote weight loss,” Dr. Nandi says. “This is completely incorrect! The late night commercials selling colon cleansers to rid one of stool ‘spackled’ to the inside of the intestine are completely false and are purposefully creating misinformation in order to sell a solution to innocent and naïve customers.” Try these 40 tips to lose weight instead.

Stool softeners in particular are often helpful after C-sections, according to Dr. Steth. “Laxatives can be very helpful after birth especially in women who have had a third or fourth degree laceration and should not strain to have a bowel movement.” Learn other secrets no one tells moms-to-be about birth.

“Some laxatives may bind up or interfere with medication absorption, such as some antibiotics or cardiac medications,” Dr. Nandi says. Always consult with your physician or pharmacist on any potential drug interactions or binding up of your meds.” And be aware of these 11 signs that your medications could be making you sick.
